ADVICE on an 03 impreza engine rebuild please!
Hey guys, I haven't posted for a little while because my beloved impreza has been testing for almost a year until I decided what to do with with it. Last year after a major overhear due to a corroded radiator it developed internal detonation problems thus leading to my engine being opened up. ... Now I'm not a pro when it comes to cars so please don't give me any technical terminology, but 2 of my stock pistons need replacing therfore needing a full set. Iv opted for cosworth pistons and rods because the price difference isn't that substantial compared to subaru parts and im very happy to have a more resilient and reliable engine. But my MAIN question to you guys is, even though my crank is supposedly ok, is it worth getting a forged crank too???? I don't plan to up the HP to an astonishing level as i have other priorities in my life at this time. but i love the thought of knowing my car is at a good "base level" if ever I wanted too . Thanks in advance people.

While it's out get as much done as you can afford to do. You'll save in the long run.
You can almost guarantee whatever you don't do will need doing shortly after the engine goes back in.
Alan Jeffery enginetuner would be a good place to start.

Hi Marc
Your crank question is an easy one to answer, all you need is a good stock Subaru one. As long as it checks out nicely, it'll be fine.
You can't go wrong with Cosworth parts, although being fair it's the build quality that's most important.
If you consider a ready built short block is the best way to start, give me a call!
